Abstract High purity ammonium metavanadate (NH4VO3) is the most vital chemical to produce V2O5, VO2, VN alloy, VFe alloy and VOSO4, which have some prospective applications for high strength steel, smart window, infrared detector and imaging, large scale energy storage system. NH4VO3 is usually produced by spontaneous crystallization from the aqueous solution due to its sharp dependence of solubility on the temperature. However, hazardous chemicals in industrial effluent, include phosphorate, silicate and arsenate, causing severe damage to the environment. In this work, these impurities are selectively precipitated onto inorganic flocculants, while the vanadate dissolved in an aqueous solution keeps More >
